In reply to @udit.kumar.sahoo:matrix.orgapologies. To catch you up: we started estimating how long the concept study phase would take by considering this list of deliverables as a rough work breakdown structure and estimating the hours needed for each item. Whaddyu think?
|11:04:26||neutronstar||Sounds like starting with what GitHub recommends is a good start. When we know things that doesn't work for us we can fix that, nothing is written in stone...|
|15:01:00||tmallard||Agree w @neutronstar:matrix.org on listing teams, team perm's to pull requests as sane :)|
Power from the Debye Sheath, a brief history in this updated visio from sept: https://drive.google.com/file/d/1dXmR05A3bN6icKe6B0W8sAkYsCxf_ea9/view?usp=drivesdk
The levitation zone always has dust, forever, 2.1m down was 3-billion years old, an accretion rate of 0.7pg/yr ... the max current near the Van der Waals radius zone below that the regosol is an electrical dielectric that resists current flow in Siemens = 1/Ω's, mho.
White Spider rover was supposed to study it, at first a spiral of sensors, then an open conductive net, this scales to Mwh, back to protecting the lander.
The solution became the new spacesuit, it has μ-meterorite neoprene, keeps out dust, 14oz/yd, 5.5lb cloth only. Circular pipes hold an upper & lower section the bottom ring has "poles", each wired for current the top 2 are power antennas.
The circuit draft diagram has the day-night anode/cathode switch, this takes only 20-minutes: https://drive.google.com/file/d/1LKx8obrDb8fH2urQ9JFjCw5UhJ6A7GpV/view?usp=drivesdk
The big events charge the dirt to -700v/m in 45-min the dissipation takes 20-days, event noise puts enough power into > 1Ghz freq's to open the dielectric gates to current flow.
This all pushed to using antennas not stakes to gain voltage variance, the avg Debye is right at the surface < 15cm/6", events charge deeper, stakes then are useless.
So the bottom pipe takes the +10v to -4.4kv range against the antennas in a load driven circuit where by design to get 28vdc.
By leakage rate only it's 300w ballpark, use 1.2986Ghz on the bottom pipe and current is only limited by demand and wire size. Charge surrounding a lander 1s: https://drive.google.com/file/d/1Q_-0gcag6YwSqJr_Yx0sl6XnPJrw7CC1/view?usp=drivesdk
This has the dissipation & reversal rate calcs: https://drive.google.com/file/d/1YYGtOPo2s8131MpKAWLw9dPujMYh7TkG/view?usp=drivesdk

The moon is an astronomical leaky capacitor, its soil is charged enough a sealed sample was opened recently and the regosol had eaten through all the seals, allowing air into the container.
I can't recommend subterranean living on the moon from this, the soil you're in goes to -500v passing earth's plasma tail and remains charged for decades sealed.
Questions welcome, it's kinda basic power circuitry, the dielectric begins immediately below the conduction layer and charges go too deep for grounding rods, antennas and surface poles appear to be practical.

In reply to @neutronstar:matrix.orgexcellent, good to hear
|00:45:57||Patrick Donovan|| |
In reply to @tmallard:matrix.orgawesome thanks
|05:38:27||Patrick Donovan||A mundane but necessary update for making life a little easier: I started putting together a list of Google Drive file naming rules here. Please let me know what you think by commenting in the doc or in issue #99 on Github.|
|19:57:18||Patrick Donovan||Redacted or Malformed Event|
|19:58:30||Patrick Donovan||does anyone have experience using Zapier? There's a way to arrange their integration such that (for example) changes to a google doc can be automatically reflected by pull requests to a document stored in github.|
|22:18:52||Patrick Donovan changed their display name from paurd to Patrick Donovan.|
|11 Dec 2018|
|01:09:43||Carlos Gonzalez-Rivera||Patrick Donovan: This Zapier stuff looks interesting. I don't think I'll be able to make it to the meeting tonight pals =/|
|01:41:25||udit.kumar.sahoo||Guys.. Same with me as well. 😞 @paurd:matrix.org @suzi.bianco:matrix.org|
|02:35:03||outbound||You will both be missed.|
|02:50:40||suzi.bianco||Yes you will!|
Two links to a machine & 1st flight, Debye protection & more:

|09:22:19||Carlos Gonzalez-Rivera changed their display name from cagonzalez8 to Carlos Gonzalez-Rivera.|
The RFI posted above is only for Astrobotics not NASA, from comments last night, they'd need a heavy reworking to play their game. The focus with NASA is the CLPS company list for Orion test flights to IIS.
I can help proofing to publish ready steps on them, this was a draft of how the machines.
|15:37:48||tmallard||Oops, how they start with foundational needs, the Debye work most persuasive against underground living.|
Most all of the lit favors subterranean living, and, aside from a massive amount of digging there are few advantages over surface structures able to defend against meteoroids & rad.
Leaded glass may have another additive for gamma, the spacesuit uses neoprene for meteorites.

Did you create this Diagram? > A worksheet a draft of categories & subcategories for first flight on the second sheet: https://docs.google.com/spreadsheets/d/19UrHmW6NDYZrAubZPsud7U3Ma2UcgxzUopb2HsYBN88/edit?usp=drivesdk
And how would I utilize this?

|01:19:03||tmallard||Just enter things, as little or much on an item, the dropdowns are a try at bucketing things at subsystem level for searches.|
|03:50:29||Patrick Donovan|| |
In reply to @tmallard:matrix.orgyour file "mash_all_dd" is set to read only at the moment so I can't test it out. I gotta say that a searchable database that takes advantage of a consistent naming system is useful (having worked a government desk job with a database that seemed to be from the 80's, I can't imagine how much worse it would have been without that database).
Before we get to that though: have you had a chance to take a look at github issue #99 and/or the draft file naming standards here? I'm curious what you think.
Oh, will allow edits, that post mostly to give people ideas.
I got the naming paper & was going to see if a macro or vba for the naming in excel can pull the last used name & insert new ones into a column until a db is done.
Had to convert to sheets to allow edits.
And, I can do formatters for naming, type lowercase, it can increment & fill whatever format is needed & pretty sure can be added to any sheet, you can in excel.
Ok, for naming use case is forms textboxes to paste in or enter the filename and ext., these in columns for each convention internal & for doc's like RFIs,
Choices for each are dropdowns from a 2nd datasheet to define & maintain.
Last box gets the result, that can be auto copied to clipboard if allowed, or, be selected on-enter of the last entry and inserted into a column as a datasource to bind to vs a db.
Not sure how to in sheets, there's a tab for this in office apps, library run, gotta go.
